Anki opens with only menu bar visible, rest of the window is blank

Hello,

I’m encountering an issue where Anki opens but only the menu bar is visible, and the rest of the window is completely blank. Here are the steps I have tried so far:

  • I have disabled all add-ons to rule out conflicts, but the problem persists.
  • I changed the display driver option to “software,” but that did not resolve the issue.
  • I uninstalled Anki completely, restarted my computer, and reinstalled Anki, but the problem remains.

Here are my system and Anki version details:

  • Anki version: 24.10 (eae9bbc4)
  • Python 3.9.18 Qt 6.6.2 PyQt 6.6.1
  • Platform: Windows-10-10.0.26100

Any advice or suggestions on how to fix this would be greatly appreciated!
Thank you in advance.

You’re on the right track here, I think. But you should try all of the available options, and make sure you restart after each change. Troubleshooting - Anki Manual

If none of them work – what changed when this started happening? Was this a fresh install, or an upgrade from another version?

Thank you for the suggestions!

I have tried all available display options, including switching to “software” and restarting after each change, but the issue persists.

Regarding your question, this problem occurred after I upgraded from a previous version of Anki. It was working fine before the upgrade. I didn’t install any new add-ons or make major changes to my system recently. It seems the issue began right after updating.

Any further advice would be appreciated!

Im not sure but I would try running Anki from the terminal and see if it spits out any errors, it could give some clues as to what is breaking things

I just did the math and realized you’re using the beta version. You should –

  1. Make sure this is still happening using the most recent beta release.
  2. Read the beta thread and make sure this isn’t already reported – Anki 24.10 Beta .
  3. Report it in the beta thread.

Then, as an alternative to get you running again, you can go to File > Switch Profile > Downgrade & Quit – and then install the most recent released version of 24.06.

Thank you for the follow-up!

Actually, I completely uninstalled Anki, restarted my computer, and then installed the official release version (not the beta), but the issue still persists. The same problem occurs with only the menu bar visible and the rest of the window being blank.

Did you try the Troubleshooting steps again? Including all of the video driver options?

Yes, I went through all the troubleshooting steps again, including trying all the video driver options and restarting after each change, but unfortunately, the issue still persists.

Do you have any other ideas on what might be causing this?

Thank you for your continued support!

Have you looked at Windows - Anki Manual?

  • Do you remember what version of Anki you had installed and functioning on this system before you upgraded (before your original post)?
  • Go to Help > About, click Copy Debug Info, and paste that entire result when you respond.
  • Do you see any errors when you run Anki from a terminal window – Startup Issues - Anki Manual ?

Could you provide a way to run Anki using cmd or Powershell?

I think running Anki by just opening through terminal will do anything but do dumps. Unless you’re in Linux.

Anki 24.06.3 (d678e393)
Python 3.9.18 Qt 6.6.2 PyQt 6.6.1
Platform: Windows-10-10.0.26100

I posted a link to the instructions for doing this in Windows just above your post.

You didn’t answer this.

I don’t think that’s the entire result.

Should I assume your screenshot is a response to this?

Mistaken

I was using version 24.06.3 Qt6 of Anki before I upgraded to the latest beta version. After the update and restart, Anki stopped displaying content properly. I tried downgrading to the previous version, but the issue persisted. Around the same time, I updated my GPU drivers and optimized the 3D settings on my RTX 4070, including enabling Super Resolution. Even after reverting these settings and fully uninstalling Anki using Revo Uninstaller Pro, followed by deleting all related files, the problem remained. I ran the anki-console.bat file, but it didn’t show any errors, and the debug information appeared blank (though it was copyable).

It seems the issue might be related to the GPU settings, as everything else on my system runs fine. I’d appreciate any further guidance on resolving this.

Okay, that description makes things clearer.

We might be chasing our tails here. If you were using 24.06.3 before just fine, and it’s not working now, then yes, it seems highly likely that the changes you made to your system drivers are the reason why changing the video drivers in Anki isn’t helping.

Let’s see if someone else has advice about how to return your drivers to a workable configuration!

This may be a bit time-consuming but do you have an onboard video from the CPU that you can reproduce, if the issue occurs the same?

Maybe open Task Manager and take a look at anki.exe. It should spawn QtWebEngineProcess.

If there’s no QtWebEngineProcess, close Anki, open Command Prompt and try to run Anki with this command.

set "QTWEBENGINEPROCESS_PATH=%LocalAppData%\Programs\Anki\lib\PyQt6\Qt6\bin\QtWebEngineProcess.exe" & "%LocalAppData%\Programs\Anki\anki-console"

If it doesn’t help or QtWebEngineProcess exists, maybe run this command at first to tell Anki and Qt to output more debugging information

set ANKIDEV=1 & set QSG_INFO=1 & set "QT_LOGGING_RULES=qt.webenginecontext.debug=true"

and then try to open Anki using this command

set "QTWEBENGINE_CHROMIUM_FLAGS=--no-sandbox --disable-gpu" & "%LocalAppData%\Programs\Anki\anki-console"

and also this one

set "ANKI_SOFTWAREOPENGL=1" & "%LocalAppData%\Programs\Anki\anki-console"

If nothing worked, and changing the video driver from the Preferences screen to Direct3D, OpenGL or Software didn’t help either,
